Late night studies

Late night studies  ....when this word comes on my mind i think of a full glass or mug of tea  or coffee, lots and lots of  tension,big big books and writing  notebook and pen....its not good to study at night since night are the natural medicine  for our brain and if our brain do not get rest....the next whole day will be terribly  effected....a normal person should get at least  7 to  8 hours of sleep.when u do the studies whole night  n prepare  for exams ..you think that you are studying  really well and exam is going to be superv but what happens in the exam you forgot  every thing....so it is advisable to give rest your brain,,,,for this you can listion good music,sit alone and talk to yourself,know about yourself....go in flashback n keep smiling i know it' sounds stupid  when some one ask you to do all these things but it really works...lets put all nervousness  and tension  in the garbage  and refresh our minds..
